The only other special thing reiserfs does with the page cache is file
tails.  I don't suppose all of these pages are index zero in files
smaller than 4k?

Ahhhhhhhhhhhhh !! I am so blind :(

I have been suspecting reiserfs all along, since its executing
fallback_migrate_page(). Actually, these buffer heads are
backing blockdev. I guess these are metadata buffers :( 
I am not sure we can do much with these..

Thanks,
Badari
